\n \u984c\u76ee: Fragmentation function related measurements at Belle<\/p>\n
\u6982\u8981:
\n The formation of massive final state hadrons out of nearly massless, high-energetic
\n partons is governed by the strong interaction, described by Quantum-Chromo-Dynamics
\n (QCD). As nearly all the visible mass of the universe is created via QCD, it is of particular
\n interest to understand how such hadrons are formed in the fragmentation process.
\n Additionally, fragmentation functions (FFs) are universal objects that can be used to learn
\n about the spin, flavor and transverse momentum dependence of the structure of the
\n nucleon such as studied in deeply nelastic lepton-nucleon scattering or hadron-hadron
\n collisions. Unfortunately, fragmentation functions cannot be calculated from first principles and need to be measured instead. The cleanest way to access them is in the electron-
\n positron annihilation process as no hadrons exist in the initial state and at leading order a clean quark-antiquark pair is produced. The Belle experiment at the KEK-B collider has accumulated more than 1 ab-1 of e+e- data which has been used to extract various fragmentation related measurements for unpolarized and polarized fragmentation of light hadrons as well as various heavier hadrons. Recently, the explicit transverse- momentum dependence of pions, kaons and protons was studied. An introduction to fragmentation functions will be given before these Belle related measurements will be discussed.<\/p>\n
